9 kHz to 3 GHz
Professional signal generator for
production, laboratory and service
The R&S SM300 is a favourably priced signal
generator for applications in the 9 kHz to 3 GHz
frequency range. The instrument features a broad
scope of functions, outstanding technical characHigh signal quality
teristics and compact design.
In addition to standard analog modulation modes,

Rohde & Schwarz will quickly find the menu items they know from other Rohde & Schwarz instruments.
The bright TFT colour display with 320 x 240 pixel resolution allows traces to be read even at odd
angles or when the incidence of light is unfavourable.

Applications
Its broad scope of functions makes the R&S
SM300 the ideal instrument for diverse use, e.g.
in digital and analog mobile radio or for EMC
applications.
Generation of precise test signals for the following applications:
lab, service, production and quality assurance
Provision of digitally modulated signals in the 9 kHz to 3 GHz frequency
range (e.g. with the R&S AMIQ as an external baseband signal source)
Signal generation and modulation (AM, pulse) for EMC measurements
of components (EMS)
Functionality testing of components in production
Semi-automatic measurements by pressing a button to retrieve stored
settings

The RF characteristics of the R&S SM300 set new standards in the lower price segment. Its low wideband and single-sideband phase noise make the R&S SM300 the
ideal tool for use in labs, test sets at colleges and universities, in service and at production sites.

Internal I/Q modulator for baseband signals
The internal I/Q modulator expands the range of R&S SM300 applications to
mobile radio as well, thus making vector modulation of baseband signals possible
for GSM, 3GPP or IEEE 802.11 b, g.
Wide variety of analog modulation modes
The R&S SM300 can handle all analog modulation modes: AM / FM / M / pulse.
It is used for generating interference signals in EMC applications, e.g. automobile
industry, military, avionics, or for commercial measurements.
Frequency sweep, level sweep
The R&S SM300 makes it possible to sweep the internal LF generator as well as the
RF frequency and the RF level in user-selectable steps.

RF Signal Generator R&S SM300
USB interfaces
The USB host interface provided as standard links the instruments to the PC world. The bus ensures
high data transmission rates at low cost. Other peripherals (e.g. printers) can be addressed via another
USB interface.
Identical housing
All instruments based on the Family 300 concept have an almost identical “face”, a 5.4-inch VGA TFT display,
front-panel control elements, protective guards and a handle that can be adjusted to different positions. Only
the connectors on the front and rear panel vary depending on the instrument type.
If the protective guards and the handle are removed, the R&S SM300 can be installed in a 19-inch rack.
Owing to their slim design, two instruments of the Family 300 can be placed next to each other.
Uniform operating concept
All instruments are similarly operated on the basis of the high-end devices from Rohde & Schwarz.
Most operations are menu-controlled so that no device-specific keys are required. Only the four unit keys
for entry confirmation are configured separately.
